Answer:
x = -8
y = 9
Step-by-step explanation:
to solve this expression using simultaneous equation, we would say let
y =9............................................. equation 1
6x + 5y =-3............................................equation 2
substitute equation 1 into equation 2
-3 = 6x + 5y............................................equation 2
6x + 5(9) = -3
6x + 45 = -3
collect the like terms
6x = -3-45
6x = -48
divide both sides by the coefficient of x which is 6
6x/6 = -48/6
x = -8
therefore y = 9
x = -8
Answer: it says independent work

Answer:
7^40 is umm I don't know sorry
Step-by-step explanation:
But hopefully it's helpful.
Numbers 5 and over round up to the nearest 10. Numbers like 164 would found to the nearest 10 of 160 because the last number (unit) is below 5, so it rounds down. I hope this helps but you can find tutorials on google good luck!
For 11. Not all of the y values (outputs) are consistent with the pattern
